Warning signage is being removed from locations around Lough Neagh following this past summer’s blooms of toxic blue-green algae.
But as BBC News reports, it could be years before the ecological impact on the lough is fully understood.
Ulster Angling Federation chair Gary Houston claimed that the collapse of the Lough Neagh fly, attributed to the cyanobacteria blooms, has had a knock-on effect on all other species in the area — most notably its native trout and eels.
A spokesperson for the Northern Ireland Environment Agency (NIEA) said the fly species was not previously monitored as it was “commonplace and not a protected feature” but confirmed they are “a key trophic (food) component of the Lough Neagh ecosystem”.
“We’ve been damaging the ecosystem in Lough Neagh now for 60 years or so and we’ve been doing it knowingly for 50 years, but we’ve got away without the acute impacts [until now],” said Dr Adam Mellor of the Agri-Food and Biosciences Institution (AFBI).
All parties acknowledge that the current crisis is the result of multiple factors over decades — including climate change, changes in agriculture and the presence of invasive species — and some believe it could take just as long to turn it around.
